Hi,
Are you possibly trying to use an ICA Driver Ver.4.1.3a (Mac), with the misd-mac-ijscanner15f-4_1_3-ea21_3.dmg file name?
If so, see Precaution, for example, item 6.
How to scan using AirPrint is described in https://www.canon-europe.com/support/consumer_products/apple_airprint_guide/#Scanning_Mac .
About AirPrint - Apple Support
A Canon MG7750 is mentioned in his article as a model supporting the driverless AirPrint technology. An AirPrint-enabled printer is compatible with macOS, and does not require the installation of drivers (providing that the printer and the computer are conneced to the same network).

Hello alistair35,
The article 'You do not have permission to open the application' when using a scanner on Mac - Apple Support
could perhaps be of interest to you. Canon has some details in https://support.usa.canon.com/kb/index?page=content&id=ART180175 .
Hi,
I get a similar error message - although not identical. Mine says "You do not have permission to open the application “Canon IJScanner15f”.
I then get a 'Failed to open a connection to the device (-21345). This only occurs when trying to scan - printing is working fine. I have tried deleting and reinstalling the printer, and all of the options for Secure AirPrint / Airprint and Canon IJ Network and get the same behaviour. It's worth noting the printer and scanner have worked fine for several years / Mac OS versions, it just seems to be an issue in Big Sur.
I have downloaded and installed the following version of printer driver :
mcpd-mac-mg7700-16_40_1_0-ea21_3.dmg
Any further thoughts would be welcome - thanks!
Hi Jan,
Thank you very much for pointing me at that solution / workaround - that worked perfectly. Thanks so much!
Downloaded it just now.
You're welcome! Glad to hear that it worked.
